Archivio Istituzionale della RicercaThe application of more stringent emission regulations for pssenger cars in Asian and South American countries is challenging due to the presence of low quality diesel fuel [1] which enhances the risk de-activation of aftertreatment systems due to higher sulfur levels [2]. In this context, the impact of high sulfur fuel on the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC) performance was experimentally tested for degreened, sulfated and de-sulfated aftertreatment components. The impact of different space velocities on degreened, poisoned and de-sulfated system was examined and compared considering light-off curves for CO and HC.

Abstract
The application of more stringent emission regulations for pssenger cars in Asian and South American countries is challenging due to the presence of low quality diesel fuel [1] which enhances the risk de-activation of aftertreatment systems due to higher sulfur levels [2]. In this context, the impact of high sulfur fuel on the Diesel Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC) performance was experimentally tested for degreened, sulfated and de-sulfated aftertreatment components. The impact of different space velocities on degreened, poisoned and de-sulfated system was examined and compared considering light-off curves for CO and HC.
